I had the same problem few months ago. 
 
I tried everything i could think of to fix it.
Ran CCleaner
Disabled all addon's
Deleted browser cache
Tested with Microsoft edge browser
Tested with a tablet
 
 
I notice EVGA is allowing facebook.net to tracker us on evga website and forums again.  
 

Ahh okay, thanks rjohnson11 for passing this on
 
Yet I find it still weird though, it would be nice to know what is causing this, only then the problem can be taken head on with.
As a beta tester myself from x-3dfx and several community forums from the Descent Community,  this was something I always enjoyed doing.
Mainly seeking bugs, making bug reports, thereby helping communities getting cleaner forums, to drivers to game versions in such sense.
 
All the webmaster would have to do is compare this website build they have now with a previous one where the uploader worked, then they can see where it went wrong and what causes this to occur.
That way a work around or a fix can be made, anyways that is what I did when beta testing for DXX-Rebirth and x3dfx drivers during my 3dfx days.
 
But I guess it's far more complicated these days to even fix such a small thing.
Thanks for your replies though, that does show that I am not the only one with this particular issue
 

Yeah well it maybe that only European EVGA forum members are effected to the issue.
Might be an idea for the Webmaster to compare the Euro boards with their Non Euro boards and see what makes the difference for this to break.
Then the problem cause may be found and be fixed, sorry if I think to simplistic on the matter, but this is what I would do.

hah yeah! Well kinda funny now though because now  seems it kind of uhm fixed it's self leeel 
So here is what I did xD
 
I go to my upload avatar thingie:

 
It says no larger than 200KB, which should be no issue :)
 
My file is 200px and only 11.4KB in size, which is perfect :)

 
The I wanted to upload I got this odd error like every time I tried to upload my avatar, I have to hope I can recreate this error because I forgot to make a screenshot of it...
 
Anyways after the 4th try it worked
 
Yaaaays! Goldie is Happehs again, my avatar is one of my main OC's named Frostora my Girlfriend made it with Paint Tool SAI 
 
**Update**
The error still happens it seems:

 
I just have to try a few times before it works, seems like some random ting still happening.
 
****Update 02****
Yeaps keep trying and it works

 
Skittles is my other OC also made by my Girlfriend
 
Profile pictures by the way are not affected by this bug, it's only with the avatars, just to keep in mind and away from the confusion
My workaround is keep trying to override the big, forcing it to work, even tho this bug should get fixed so a workaround is not of need right
Anyways I hope this helps you guys somehow

Strange, seems to be working now for me as well. I did send an email to EVGA so maybe someone has fixed this.

Yeah as for my avatar it's Frostora  my main Original Character for my Impressive Title & Feral Heart Roleplay & Derp group named Majestic Ferals :)

They took me about 2 to 3 hours each to make to get the coloring just right rofl xD
I used the default Feral heart Create a Character tool, these are not even presets...
My goal was to get the max out of the default editor xD And that worked out just fine really, making Presets isn't easy so I kind of let that idea fade lol
 
These are old school, we have our own private maps , we rarely play since most of our members have real life going on and such rofl, but it's always something I do keep doing with the ones that still feel like having a talk about things or other things we use Ferla Heart like Impressive Space as Virtual chat programs  and it's game that allows you to be your OC in any form you want it to be Canine or Feline based.
 
Anyways sorry for the offtopic bit there, even bcavnaugh has his reply now xD

Yes the problem has occurred again but this time I have a direct contact to handle this specific issue and I have forwarded this to him.

Ah many thanks man, I will keep testing it, for workarounds as well and I will help keep this up to date if it ever happens again as well

Have you tried turning it off and back on?

Yes sir I have, no change though

I was just being a smart butt.
 
Nothing you can do about it, you will just have to wait until webmaster figures out what's causing it to happen to members at random.
 
 

Oh it's fine man, all cool
it's that I have autism and dyslexia, sarcasm and jokes are always hard for me to determine if they are serious or not.
Most I read as insults, but not to worry I just misread you, which I have a lot with such things
Oh wells, it happens and I am fine for the rest
 
Well I am sure this will be fixed, even though I do wonder what causes it, that is always something that interests me of how such things happen
